[Rack] more network shenanigans

Just a couple of comments on the Minotaur upgrade. We used to see a
list of serial ports and what was connected to them, in /etc/motd or
/etc/issue. This doesn't show on login anymore. From my notes, the old
serial configuration was:

ttyS0 switch2 console
ttyS1 bikeshed console
ttyS2 apcupsd
ttyS3 noisebridge-baron

Secondly it looks like the serial ports are getting enumerated
differently and hence the device names have changed. So gate used to
be on /dev/ttyS3 but now there is no ttyS3 and it's moved to
/dev/ttyS5.
